Informe del Seminario Regional sobre Sistemas Ambientales y Estrategias para Ampliar la Frontera Agropecuaria en América Latina = Report of the Regional Seminar on Environmental Systems and Strategies for Extending the Agricultural Frontier in Latin America

Contiene los antecedentes y el resumen de los debates del seminario que tuvo como propósito hacer un aporte a la ejecución del proyecto del mismo nombre cuyo objetivo básico es propiciar metodologías viables que tiendan a disminuir el costo ecológico de las transformaciones y a formar silvoagrosistemas sustentables, y que puedan ser utilizados por los planificadores y encargados de proyectos de desarrollo agrícola y regional en áreas de expansión de frontera agropecuaria.

Disinfection protocols to prevent cross-contamination between dental offices and prosthetic laboratories

Control of cross-contamination between dental offices and prosthetic laboratories is of utmost importance to maintain the health of patients and dental office staff. The purpose of this study was to evaluate disinfection protocols, considering antimicrobial effectiveness and damage to the structures of prostheses. Solutions of 1% sodium hypochlorite, 2% chlorhexidine digluconate, 50% vinegar and sodium perborate were evaluated. Specimens were contaminated in vitro with standardized suspensions of Candida albicans, Streptococcus mutans, Escherichia coli, Staphylococcus aureus and Bacillus subtilis spores. Disinfection by immersion for 10. min was performed. Final counts of microorganisms were obtained using the plating method. Results were statistically compared by Kruskal-Wallis ANOVA and Dunn's test. The surface roughness of 40 specimens was analyzed before and after 10 disinfection cycles, and results were compared statistically using Student's t test. The solution of 50% vinegar was as effective as 1% sodium hypochlorite and 2% chlorhexidine against C. albicans, E. coli and S. mutans. The sodium perborate solution showed the lowest antimicrobial effectiveness. Superficial roughness increased after cycles in 1% sodium hypochlorite (p=0.02). Solutions of 1% sodium hypochlorite, 2% chlorhexidine and 50% vinegar were effective for the disinfection of heat-polymerized acrylic specimens. Sodium hypochlorite increased the superficial roughness. © 2013 King Saud Bin Abdulaziz University for Health Sciences.
